Description:
The Queensland Government is upgrading 11km of the Bruce Highway between Caboolture and Steve Irwin Way, as part of a $662.5 million project to reduce congestion and improve flood immunity. Split into two separate construction contracts, Acciona Infrastructure Projects Australia (ACCIONA) delivered Contract 1 between Caboolture-Bribie Island Road and Pumicestone Road, with a contract value of $150 million.
Contract 1 involved upgrading the Bruce Highway from four to six lanes, as well as upgrades to creek crossings, improvements to entry and exit ramps at interchanges, and the installation of Smart Motorways technologies to improve safety and manage traffic flow.
The initial IS Design Rating was delivered by Jacobs SMEC Design Joint Venture in 2019-2020. ACCIONA delivered the As Built Rating for Contract 1.
Rating Highlights
| Category | Credits | Achievements/Risks |
| Climate Change Adaptation | Cli-2 | Achieved Level 3 and 3.52 points
The project demonstrated exceptional performance in the assessment and implementation of climate change adaptation measures. |
| Energy | Ene-1 | Achieved Level 2.15 and 6.81 points
17% reduction in fuel and electricity consumption through value engineering reductions in haulage, construction lighting supplemented by renewables, and an upgrade from HPS to LED street lighting. |
| Water | Wat-1 | Achieved Level 2.73 and 4.33 points
17.3% reduction in water use for various construction works. |
| Wat-2 | Achieved Level 2.96 and 2.61 points
98% replacement of potable water with non-potable water. Almost all non-potable water was sourced from local sources, site compound roofs, ponding water on-site and sediment basins. |
|
| Materials | Mat-1 | Achieved Level 2.69 and 5.68 points
25% reduction in lifecycle emissions through the use of EME2 for an extended design life for the road pavement, 15% recycled asphalt pavement content (RAP) in some asphalt mixes, 30-44% cement replacement in concrete mixes off a base case of 20%. |

| Invertebrate-Sensitive Road | 04/12/2023 | | Australian First
(Piggyback) |
The project was one of the first in Australia to incorporate an invertebrate-sensitive road design for the Richmond Birdwing Butterfly into their design.
The project recognised that road assets across Australia typically focus on implementing fauna sensitive designs, but there was a distinct lack of consideration for invertebrates, particularly for a species that is classed as ‘vulnerable’. Just south of the Lagoon Creek site, the following flora species were planted to connect and increase the Richmond Birdwing Butterfly’s habitat between the Sunshine Coast and Greater Brisbane:
